With a clipper you can use the blade to get a good amount of heat. The cooling spray reduces the temperature of the blade and allows you to start working immediately. Does not contain oil, so no wiping is required.
[How to use] For cooling purpose: Please take about 7.9 inches (20 cm) away from the engraved surface of the replacement blade, and use within 3 seconds. For cleaning purpose: Disassemble the replacement blade, spray directly into the clog area, and use it within 3 seconds
